For EZGO golf cart users—whether you're navigating the greens, maintaining large properties, or enhancing your cart for outdoor adventures—the battery is the central component that defines your vehicle’s capability. A dependable power source determines your driving range, speed, and acceleration, while also influencing long-term maintenance and running costs.
While lead-acid batteries have traditionally powered most carts, more owners today are switching to lithium batteries for their EZGO models. Lithium options are lighter, recharge faster, and provide far longer lifespans, delivering better performance and long-term savings.
Below, we’ll help you identify the best electric golf cart batteries for EZGO vehicles available in 2025.
Understanding Golf Cart Batteries and the Importance of Deep Cycle Design
Golf cart batteries differ from car starter batteries. Instead of producing a quick burst of energy to start an engine, they supply steady power over extended periods—this is known as deep-cycle performance. Deep-cycle batteries can handle frequent charging and discharging without premature wear, making them ideal for electric golf carts that draw power continuously.
Main Battery Types for EZGO Golf Carts
| Battery Type | Description | Advantages | Limitations |
|---|---|---|---|
| Flooded Lead-Acid (FLA) | Traditional liquid-electrolyte design using water and sulfuric acid. | Lowest initial cost | Heavy, requires frequent maintenance |
| AGM (Absorbed Glass Mat) | Sealed lead-acid type with glass fiber mats holding the electrolyte. | Leak-proof, minimal upkeep | Slightly higher price, shorter lifespan than lithium |
| Lithium-Ion (LiFePO4) | Modern lithium-iron-phosphate chemistry with advanced rechargeability. | Lightweight, quick charging, long-lasting | Greater upfront investment |
Why Deep-Cycle Design Is Key
Deep-cycle batteries maintain consistent voltage over hours of use. Lithium-based batteries, particularly LiFePO4, outperform lead-acid versions in nearly every respect—offering up to a decade of service life and twice the usable capacity (around 90% discharge depth versus 50% for lead-acid).
In summary, while lead-acid options are cost-effective for casual use, lithium batteries deliver superior efficiency, lower lifetime cost, and greater reliability for EZGO owners.
EZGO Golf Cart Models and Voltage Compatibility Guide
Each EZGO model runs on a specific voltage configuration, and that determines which battery pack you need. Identifying your cart’s system voltage is the first step when replacing or upgrading batteries.
EZGO Voltage Systems Overview
| System Voltage | Typical Battery Layout | Common EZGO Models |
|---|---|---|
| 36V | 6 × 6V or 3 × 12V | EZGO TXT, Medalist (older series) |
| 48V | 6 × 8V or 4 × 12V | EZGO RXV, Freedom, Elite |
| 72V | 6 × 12V or lithium pack | EZGO high-performance conversions |
How to Check Your EZGO Voltage:
- Count the number of battery cells (each lead-acid cell equals 2 volts).
- Refer to the data label under the seat or beside the charging socket.
- Inspect wiring—batteries connected in series increase voltage, while parallel connections expand capacity.
Tips:
- Ensure your battery pack voltage matches your controller’s rating.
- Never mix new and old batteries or different voltages—it can harm the controller.
- Verify charger compatibility before upgrading to lithium.
